unacceptable:
Change to a lighter weight paper. See page

Check the machine’s environment: very dry
(low humidity) or high humidity (higher than
80% RH) conditions can increase the
amount of background shading.

Condition Suggested solutions
Vertical repetitive
defects
If marks repeatedly appear on the printed side
of the page at even intervals:
The toner cartridge may be damaged. If a
repetitive mark occurs on the page, print a
cleaning sheet several times to clean the
cartridge; see page 10.4. After the printout,
if you still have the same problems, remove
the toner cartridge and install a new one.
See page 10.5.
Parts of the machine may have toner on
them. If the defects occur on the back of the
page, the problem will likely correct itself
after a few more pages.
The fusing assembly may be damaged.
Contact a service representative.
Background
scatter
Background scatter results from bits of toner
randomly distributed on the printed page.
The paper may be too damp. Try printing
with a different batch of paper. Do not open
packages of paper until necessary so that
the paper does not absorb too much
moisture.
If background scatter occurs on an
envelope, change the printing layout to
avoid printing over areas that have
overlapping seams on the reverse side.
Printing on seams can cause problems.
If background scatter covers the entire
surface area of a printed page, adjust the
print resolution through your software
application or the printer properties.
Misformed
characters
If characters are improperly formed and
producing hollow images, the paper stock
may be too slick. Try a different paper. See
page 5.1.
If characters are improperly formed and
producing a wavy effect, the scanner unit
may need service. For service, contact a
service representative.
Page skew
Ensure that the paper is loaded properly.
Check the paper type and quality. See page
5.1.
Ensure that the paper or other material is
loaded correctly and the guides are not too
tight or too loose against the paper stack.
